David Turner e5680279b2 * many, many files: several memory optimizations were implemented to
drastically reduce the heap usage of FreeType, especially in the case
  of memory-mapped files. The idea is to avoid loading and decoding tables
  in the heap, and instead access the raw data whenever possible (i.e.
  when it doesn't compromise performance).

  This had several impacts: first, opening vera.ttf uses a ridiculous amount
  of memory (when the FT_Library footprint is accounted for), until you start
  loading glyphs. Even then, you'll save at least 20 Kb compared to the non
  optimized case. performance of various operations, including open/close
  has also been dramatically improved.

  More optimisations to come. The auto-hinter eats memory like crazy? This
  must be stopped...

* src/sfnt/ttload.c (tt_face_load_hdmx): Don't assign
        num_records until we actually decide to load the table,

Werner Lemberg 779afe4b91 * src/winfonts/winfnt.c (FNT_Load_Glyph): Use first_char in
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.

* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.


Synchronize computation of height and width for bitmap strikes.  The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes.  The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.

* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.

* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.

* src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single
argument to function.

* src/psnames/psmodule.c (ps_unicode_value): Handle `.' after
`uniXXXX' and `uXXXX[X[X]]'.

David Turner 79c23ae28a * src/sfnt/ttload.c (sfnt_dir_check): relaxed the "head" table size
verification to accept a few broken fonts who pad the size incorrectly
    (the table should be padded, but its "size" field shouldn't per se
     the spec)

2002-09-05 15:10:54 +00:00
David Turner b08fe2dc7a * massive re-formatting changes to many, many source files. I don't
want to list them all here. The operations performed were all logical
    transformations of the sources:

      - trying to convert all enums and constants to CAPITALIZED_STYLE, with
        #define definitions like

          #define  my_old_constants   MY_NEW_CONSTANT

      - big, big update of the documentation comments

    * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
    include/freetype/ftimage.h: adding support for LCD-optimized rendering
    though the new constants/enums:

      FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
      FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V

    this is still work in progress, don't expect everything to work correctly
    though most of the features have been implemented.

    * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
    targets:

      FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
      FT_LOAD_TARGET_MONO   :: monochrome bitmaps
      FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated hinting & rendering
      FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated hinting & rendering

    note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
    behaviour of the font engine is _unchanged_.

Graham Asher 320da730d4 More work on supporting fonts passed from GhostScript:
sfnt_dir_check now ignores the tables 'glyx' and 'locx' which are hacked-out
versions of 'glyf' and 'loca' in some PostScript Type 42 fonts, and will
generally be invalid.
2002-07-19 11:40:51 +00:00
David Turner fed59b7cc2 * src/sfnt/ttload.c (TT_Load_SFNT_Header): fixed a recent bug that prevented

David Turner 3314a975b9 small fix 2002-07-11 23:51:44 +00:00
David Turner 7acd73fd6a * src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttdriver.c: changing
the SFNT loader to check for SFNT-based font files differently. We now
    ignore the range "helper" fields and check the "head" table's magic
    number instead.
2002-07-11 23:41:14 +00:00
David Turner a1e45652be * builds/win32/ftdebug.c: added a missing #endif
* src/sfnt/ttload.c, src/bdf/bdflib.c: removing compiler warnings

        * src/type42/t42objs.c: removed the bug that prevented un-hinted
        outlines to be loaded
2002-06-11 20:35:58 +00:00
Werner Lemberg 877ff67887 * src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT
but FT_STREAM_READ.
Declare `stream' variable.
2002-05-28 06:03:10 +00:00
David Turner 791d83a612 * include/freetype/internal/tttypes.h, src/sfnt/ttload.c,
src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c:
        fixing the SFNT name table loader to support various buggy fonts.
        it now ignores empty name entries, entries with invalid pointer
        offsets and certain fonts containing tables with broken "storageOffset"
        fields.

        name strings are now loaded on demand, which reduces the memory
        requirements for a given FT_Face tremendously (for example, the
        name table of Arial.ttf is about 10Kb and contains 70 names !!)

        finally, this is a _quick_ fix. The whole name table loader and
        interface will be rewritten in a much more cleanly way shortly,
        once CSEH have been introduced in the sources.

David Turner d15bc0d13a * README.UNX: updated the Unix-specific quick-compilation guide to
warn about the GNU Make requirement at compile time..

        * include/freetype/config/ftstdlib.h,
          include/freetype/config/ftconfig.h,
          include/freetype/config/ftheader.h,
          include/freetype/internal/ftmemory.h,
          include/freetype/internal/ftobjs.h,

          src/autohint/ahoptim.c,

          src/base/ftdbgmem.c, src/base/ftdebug.c,
          src/base/ftmac.c,    src/base/ftobjs.c,
          src/base/ftsystem.c,

          src/cache/ftcimage.c, src/cache/ftcsbits.c,

          src/cff/cffdriver.c, src/cff/cffload.c, src/cff/cffobjs.c,

          src/cid/cidload.c, src/cid/cidparse.c, src/cid/cidriver.c,

          src/pcf/pcfdriver.c, src/pcf/pcfread.c,

          src/psaux/t1cmap.c, src/psaux/t1decode.c,

          src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.c,
          src/pshinter/pshrec.c,

          src/psnames/psmodule.c,

          src/raster/ftraster.c,

          src/sfnt/sfdriver.c, src/sfnt/ttload.c, src/sfnt/ttpost.c,

          src/smooth/ftgrays.c,

          src/type1/t1afm.c,  src/type1/t1driver.c, src/type1/t1gload.c,
          src/type1/t1load.c, src/type1/t1objs.c,   src/type1/t1parse.c:

            added the new configuration file "ftstdlib.h" used to define
            aliases for all ISO C library functions used by the engine
            (e.g. strlen, qsort, setjmp, etc...)

            this eases the porting of FreeType 2 to exotic environments like
            XFree86 modules/extensions..

            also removed many #include <string.h>, #include <stdlib.h>, etc...
            from the engine's sources where they're not needed..
2002-04-12 09:31:48 +00:00

David Turner ed54f28e4a various fixes to the FT_CMaps support 2002-03-22 17:09:52 +00:00
David Turner fd88e7c7c8 * include/freetype/internal/ftobjs.h,
src/sfnt/Jamfile, src/sfnt/rules.mk,
          src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
          src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h:

            updated the SFNT charmap support to use FT_CMaps
2002-03-22 15:02:38 +00:00
David Turner e459d742e6 * include/freetype/internal/ftmemory.h, and a lot of other files !!:
changed the names of memory macros. Examples:

              MEM_Set   => FT_MEM_SET
              MEM_Copy  => FT_MEM_COPY
              MEM_Move  => FT_MEM_MOVE

              ALLOC     => FT_ALLOC
              FREE      => FT_FREE
              REALLOC   = >FT_REALLOC

            FT_NEW was introduced to allocate a new object from a _typed_
            pointer..

            note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
            by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
            arguments.

            This results in _lots_ of sources being changed, but makes the
            code more generic and less error-prone..
2002-03-22 13:52:37 +00:00
David Turner a890c29cb0 * include/freetype/internal/ftstream.h,
src/base/ftstream.c, src/cff/cffload.c, src/pcf/pcfread.c,
          src/sfnt/ttcmap.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c,
          src/sfnt/ttpost.c, src/sfnt/ttsbit.c,
          src/truetype/ttgload.c, src/truetype/ttpload.c,
          src/winfonts/winfnt.c:

            changed the definitions of stream macros. Examples:

              NEXT_Byte     => FT_NEXT_BYTE
              NEXT_Short    => FT_NEXT_SHORT
              NEXT_UShortLE => FT_NEXT_USHORT_LE
              READ_Short    => FT_READ_SHORT
              GET_Long      => FT_GET_LONG
              etc..

            also introduced the FT_PEEK_XXXX functions..
2002-03-22 12:55:23 +00:00
David Turner 7d3a26425b * renaming stream macros. Examples:
FILE_Skip    => FT_STREAM_SKIP
           FILE_Read    => FT_STREAM_READ
           ACCESS_Frame => FT_FRAME_ENTER
           FORGET_Frame => FT_FRAME_EXIT
           etc...
2002-03-20 10:49:31 +00:00
David Turner b5713c54c3 * include/freetype/internal/psglobals.h (removed),
include/freetype/internal/pshints.h,
          src/pshinter/pshglob.h: removing obsolete file

        * include/freetype/internal/tttypes.h,
          include/freetype/internal/sfnt.h,
          src/base/ftnames.c, src/cff/cffdrivr.c,
          src/sfnt/*.c, src/truetype/*.c: updated SFNT/TrueType type
          definitions
2002-03-14 11:26:29 +00:00
David Turner 28ea6f67c3 * src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name),
src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so
	that it accepts broken fonts like "foxjump.ttf", which made FreeType
	crash when trying to load them.

	Also improved the name table parser to be able to load
	Windows-encoded entries before Macintosh or Unicode ones, since it
	seems some fonts don't have reliable values here anyway.
2002-03-05 16:12:57 +00:00
David Turner bc82f1bbef * include/freetype/ftconfig.h: changed FT_LOCAL xxxx to FT_LOCAL( xxxx )
everywhere in the source. Sames goes for FT_LOCAL_DEF xxxx translated
        into FT_LOCAL_DEF( xxxxx )
2002-03-01 02:26:22 +00:00
David Turner c03d9cf5cd * src/sfnt/ttload.c (TT_Load_Names): simplifying and securing the
names table loader. Invalid individual name entries are now handled
        correctly. This allows the loading of very buggy fonts like
        "foxjump.ttf" without allocating tons of memory and causing crashes..
